In the series below, different letters stand for various mathematical operations and symbols as indicated:

P : +

Q : –

R : ×

S : ÷

T : =

U : >

V : <

Choose the option which is correct according to the given operations and symbols.

Logic: BODMAS

​$$\begin{array}{|c|c|} \hline\textbf{Operation preference wise} & \textbf{Symbol} \\\hline\text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline\end{array}$$​​

Let's analyze all the options:

(a) 15 T 3 Q 4 P 4 Q 5 (Incorrect)

Substituting the symbols:
15 = 3 − 4 + 4 − 5
15 =7 - 4 - 5

15$$\ne$$ - 2
(b) 15 U 3 R 4 P 5 P 4 (Incorrect)​
Substituting the symbols:
15 > 3 × 4 + 5 + 4

15 > 12 + 5 + 4

15 ≯ 21
(c) 15 P 3 Q 4 R 4 T 5 (Incorrect)​

Substituting the symbols:
15 + 3 − 4 × 4 = 5

15 + 3 − 16 = 5

18  − 16 = 5

(d) 15 S 3 R 4 T 4 R 5  (Correct)

Substituting the symbols:
15 ÷ 3 × 4 = 4 × 5

5  × 4 = 4 × 5

Thus, the correct option is (d) 15 S 3 R 4 T 4 R 5
